You do have an angle finder of some sort I hope . If so what are your driveshaft and pinion angles ? If you don't you can get one good enough at Lowes or Homo Depot . It is one very handy tool if you monkey with the suspension much at all and they are cheap . set your pinion about a degree or a degree and a half less than your driveshaft and you should have no vibes , same with the front end .
